What is the difference between mitosis and meiosis?

Mitosis is a process associated with organism growth, and it involves a tetraploid cell dividing to give two genetically identical diploid cells. Meiosis is the process by which gametes are formed, and it involves a tetraploid cell dividing firstly to give two diploid cells which each undergo a further division to give a total of four genetically different haploid cells.
